DOHA, Qatar -- Third-seeded Andy Murray, playing in his first tournament since back surgery in late September, was upset by Florian Mayer of Germany 3-6, 6-4, 6-2 in the second round of the Qatar Open on Wednesday.

Top-ranked Rafael Nadal was also taken to three sets but emerged with a 6-3, 6-7 (3), 6-3 win over Tobias Kamke of Germany, while second-seeded David Ferrer joined Murray in making an early exit after a 6-4, 7-5 loss to Daniel Brands of Germany.

Murray was leading 6-3, 3-0 when the 40th-ranked Mayer started to play more aggressively, going for winners on nearly every shot. The German won 12 of the last 15 games, closing out the match with a net-cord winner to seal the win in 1 hour, 51 minutes.
